T OALL WHOM YIT MAY GONCERN:

Bc it known that I, JOHN T. COE, of Chambersburg, in the county of Franklin, and State of Pennsylvania, have invented n. new and improved Churn; ldnd I do hereby declare that the following is a. full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and letters of reference marked thereon, making a. part of this specification, of whichA- Figure 1 is a plan view.

This invention consists in the construction-and arrangement of a'pair of dushersl in such manner as to draw together the'particlcs o'fbuttcr formed in the operation of'churnng, into one mass in the centre of the c hurn, as will hereinafter more fully appear. I l

To enable others skilled'in the art to make and use ,my inverrtionLLwill proceed to describe its construction A` represents a churn ot'- oi'dinary construction,madeoblong in` this instance, which, however, isinotnecessarily tho form to be adopted. At two. points in 4the longitudinal central 4line are'bearings at equal distance lfrom the ends of the chu-rn, in which are stepped the. journals of ythe two Ver-ticaldaShers b b, which are supported at theirtops b y bands c c, u't the centre of which are circular holes forthe reception of the journnlsal` ct'- on tbp'upp'er ends-of the said dashers. '.l'he bands c c are each pivoted atone end, as seen at d, fig. 5, and at their otherl ends are vbent into the form of hooked d',which khooks'are inserted in staples e einsuch manner as to bb removed therefroniwithont any d iiliculty onV talcing o' thecover, and thus admitof the easy adjusty'mentsv of thedas'hsrs'h? In the tops of the journals a' are hollows made' to fit the ends of the shnftsh hV ofthe bevel-gcars it', said shafts being set in casings t h, rigidly placed in the cover ot the cl1urn`. The lower endspf thecasings h 71. project downward far enough to meet' the upperiends of the hollow journals a', andn l thus prevent .the dasher from jumping during the operation of the machine; so as to displace the bands cirom their staples; Thesh'afts h are adjustable in their casings h', and mesh with bevel-gears l: Zoon the shaft c, saidV shaft.being supported `in standards l l at the ends ofthe cover. The bevel-gears It' areset back tobnek, so, as

to impart 4motion in contrary directions to the gears z'g-andl through them to the dashersV b. l'.lhe dashers,ar'e each 'composed of two wingsb' b at right angles, the one with the other,'each'wing consisting of ,a four-sidedfrnmc,

the.top and bottom pieces of which are flush with each-other a't thepoints of intersection. i. The said wings-:1re l made with sides inclined to a'n equal degree, the sides of b inelining from the top inward-and those of the, wings' b" inclining from the bottom inward, so that ,the greatest lateral projectonsof the wings are at the i tops of h' and bottoms of b, and the least lateral projections Vat tho tops of b and bottoms di b', while the least lnteralfprojections of the'wings,'take`n as wl1oles,are' at the middle points of their height. The

effect of this construction is to cause the gieatest agitation ofthe` cream totnke place. near .the top `and bottom of tho churn, while the cream at the centre-remains more calm,'so f ar as the action of the dnsher is concerned. -The two dashers b are ,complementary to each other, being, arranged so that those sides of 1 the revolving wings which come nearest to each other are parallel. Now, it is evident that, since the stratum at the centre of the churn is ealmest, the tendency of the currents is to ow in that direction, and that,

consequently, theparticles of butter as they form congregate at that part. The result of the' employment of two dashcrs is to 'expel the particles from the ends of the charm-and cause them` tocollect between snid dashers. All the butter`- in. the churn then is massed at its middle part, and the aforesaid parallelism of` the sides of the wings nearest each other gives the greatest amountof room forsuch messing that can be secured i under this arrangement. The advantage of causing all the butter to collect at `the centre ofthe churn is evident,

-since it not only greatly facilitates its removal, but also secures the greatest amount ofibutter from n given amount of cream, as the natural tendency of each particle toward the centre is farsmor eicucious in the way of' preventing waste thanthe hands of .any human manipulator.

Having thus fully described my invention, what I claim as new, and `desire tofsecurc by Letters Patent, is`

. 1. A ehurn-dasl1er,conssting of two wings set at any desired 'angle with each other, said wings being made with sides inclined in opposite'directions, as a'nd for the purpose set foth. l

2. The dasher b, in combination with `the band c, hook d', and staple e, substantially as described.

JOHN T. COE.-
